West Ham United manager Sam Allardyce believes that his side has enough quality at Upton Park to grab three points from Sunderland.
The Hammers, who were promoted to the Premier League last season via the playoffs, have acquired six points at home so far this season.
"We have delivered two very important home wins and, coupled with the back end of last season, we have won six home games in a row and only conceded one goal," said Allardyce.
"We want to continue that against a very strong Sunderland side who have gone away to Arsenal and Swansea and come away with points. It will be very difficult for us."
The London club currently sit eighth in the table.
